How to fix non-working touch buttons under the screen of Fly IQ4413 phone?

Question

Android

Hard Reset did not help, the phone did not fall and was not in the rain.

Answer 1

If the rest of the display works, then most likely, there is no way and only a replacement of the display (dada, just changing the touch glass is unlikely to work).
It is not necessary to drop something, the contact may disappear from a temperature difference or bending (they sat down when the phone was in the kaman).
